E-NVH Benchmark - Tooth Frequency Response Functions

Degrendele, Karine; Le Besnerais, Jean; Pile, Raphael; Gning, Paul; Devillers, Emile; Wen, Xin

This dataset contains the tooth frequency response functions (TFRF) characterizing the response of an electric motor stator to the magnetic force excitation. The TFRF consists in loading a single tooth with a single load vector and measuring the response on the external yoke. However, for practical reasons, the experimental Tooth FRF are obtained by reciprocity, by impacting the external yoke with an impact hammer and measuring the tooth response with an accelerometer normalized by the injected force.

Acknowledgement: the authors thank the company Oros for providing an OROS OR38 32 channel data acquisition system that allowed to significantly speed-up the measurement process.
